Earth system box models are essential tools for reconstructing long-term climatic and environmental evolution and uncovering ...

CAMBRIDGE, Mass., Nov. 7, 2007 — Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon ...

Magnesium isotope geochemistry has emerged as a pivotal tool in deciphering Earth’s surface and subsurface processes, particularly in the context of chemical weathering. By studying the subtle ...

CAMBRIDGE, Mass., Nov. 7, 2007 -- Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon ...

The natural rock weathering process, while effective in breaking down carbon and storing it within rocks over thousands of years, may not provide the immediate solution to combat climate change. With ...

During the Ordovician period, the concentration of CO2 in the earth's atmosphere was about eight times higher than today. It has been hard to explain why the climate cooled and why the Ordovician ...

This study is conducted by a joint team from Chinese Academy of Sciences. They use aberration-corrected transmission electron microscopy (TEM), Electron-energy loss spectroscopy (EELS) and scanning ...

Scientists have discovered that chemical weathering, a process in which carbon dioxide breaks down rocks and then gets trapped in sediment, can happen at a much faster rate than scientists previously ...

Rocks are not eternal. Even the tallest mountain will eventually dissolve and disintegrate. Geologists call this process “weathering.” It sounds harmless enough, but weathering is one of the most ...
